Each enzyme has a temperature at which it works best. A slight increase in temperature can increase enzyme activity while a larg

e increase in temperature can cause the enzyme to become denatured. Which of the following best explains what happens when a protein becomes denatured?
A. The enzyme absorbs heat until the temperature decreases, and the reaction then continues normally.
B. The enzyme loses its shape and is no longer able to catalyze chemical reactions.
C. The enzyme breaks apart into the amino acids that originally combined to form the enzyme.
D. The enzyme unfolds and refolds into a different shape, and is used to catalyze a different chemical reaction.

liq [111]

Answer:

Cell adhesion molecules would help white blood cells to stick to the wall of the blood vessel, so they can permeate across the wall and go into the underlying injured tissue.

Explanation:

The cell adhesion molecules, also called CAMs, are a type of cell adhesion proteins on the cell's surface, they take part in the binding of other types of cells and work together with the extracellular matrix in the process of cell adhesion.  

Long story short, the protein helps cells stick together or to the surrounding tissues, thus helping on the maintenance of tissue structure and function. In fully grown mammals (including humans), CAMs play an important and key role in creating force and movement, thus assuring the organs are able to execute their function.

In their role as "molecular glue", CAMs are important participants in the cellular mechanisms of growth, contact inhibition, apoptosis and diapedesis, and when their behavior goes haywire, they are associated with afflictions going from frostbite to cancer.

The order Cetacea includes modern-day whales, dolphins, and porpoises. These marine mammals share common characteristics that ha
SVETLANKA909090 [29]

Answer:

The correct option is A. they evolved from land mammals.

Explanation:

Evolution can be described as a process through which organisms in a species change over a period of time due to the natural selection of the environment. Those organisms that have many similarities in their functions or structures are considered closer to one another and have the same common ancestors.

The properties mentioned in the question about cetaceans resembles the properties of land mammals. For example, cetaceans lack gills and breathe air. Land mammals also do not have gills and need to respire for living. The cetaceans have fin bones which are similar to the limb bones in the land mammals. Hence, these observations show that cetaceas have evolved from land mammals.
